CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 603,340, dated May 3,1898. A li ation filed December 23, 1897. Serial No. 663,200. (Nomodel.)

To all whom it may concern.

Be it known that I, JOHN ISRAEL NEWBURG, a citizen of the United States,residing at Vicksburg, in the county of Warren and State of Mississippi,have invented certain new and useful Improvements in Car-Couplers; and Ido declare the following to be a full, clear, and exact description ofthe invention such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to car-couplers of that class which are designedwith a view of ob viating the necessity of a trainman going between twocars in order to couple or'uncouple the same; and it has for its generalobject to provide such a coupler of an exceedingly cheap and simpleconstruction and one which is capable of withstanding the shocks andstrains to which couplers are ordinarily subjected and which is reliablein operation.-

The invention will be fully understood from the following descriptionand claim when taken in conjunction with the annexed drawings, in WhichFigure 1 is a plan view of portions of two cars connected by my improvedcoupler, with the operating-shaft on one car. Fig. 2 is a side elevationof the same with the drawheads in section. spective view of onedraw-head with its drawbar broken away; and Fig. at comprises enlargedperspective views of the coupling-link, together with a portion of thechain and the parts connecting the same.

In the said drawings similar letters designate corresponding parts inall of the several views, referring to which- A designates thecontiguous end portions of two cars, and B B designate the draw-heads ofthe coupler, which have their bars a connected to the cars in theordinary or any suitable manner, which forms no part of my in- Thedraw-heads B B are identical in-construction, and therefore adescription of. the draw-head B will suffice for both. Said draw-head Bis cast or otherwise made in one piece, and it has the recess 0, formedin its upper side and extending to its outer end, as shown. This recess0, as better shown in Fig. 3, comprises the mouth a, which occupies thefull height and width of the draw-head at the forward end Fig. 3 is anenlarged per thereof, and has the inclined bottom b, of concav'e form incrosssection, and the flaring side walls a, the inner pocket (1, whichhas a depending portion 6, extending to the bottom of the draw-head, soas to permit dirt and water to escape therefrom, and the longitudinalcentral groove f, which connects the mouth a and pocket (1 and is ofabout the proportional depth shown. In addition to-the recess 0 thedraw-head B is provided with a horizontal recess O, which is arranged atabout the elevation shown and communicates at its forward end with themouth a, and the vertically-disposed aperture 0 which intersects therecess 0', as shown. The said recess C and aperture C are designed topermit of my improved draw-head being connected with an ordinarydraw-head through the medium of the wellknown open link, (not shown,)the recess 0 being adapted, when such coupling is made, to receive theopen coupling-link, while the aperture 0 receives the pin which extendsthrough theopen link and connects the same to the draw-head B.

D designates my improved coupling, which has heart-shaped heads 9 at itsopposite ends.

E designates a rock-shaft which is journaled on the end of the carcarrying'the drawhead B, and has cranks h at its opposite ends and alsohas an arm 11 at its middle, and F designates a chain which is connectedat one end with one head g of the link through the medium of a clevis gand pivot-bolt 9 (see Fig. 4) and is connected at its opposite end tothe top of the car and at an intermediate point of its length to the arm7 sufficient slack being afforded to permit of free movement of the arm'5 and link D.

The rook-shaft E is provided with upwardly and downwardly extendingstop-arms 2' t the former being designed to engage the front wall of thecar-body A and limit the upward movement of the arm i, while the latteris designed to normally engage said front wall and hold the arm i intheposit-ion shown in Fig. 2. This connection between the chain F andthe arm '11 is preferably effected by a removable bolt i and in virtueof this it will be seen that the portion of the chain between the arm '5and the link D may be lengthened or shortened, as desired, so as tonormally hold the link in the approximate horizontal position shown inFig. 2 or in an inclined position, so as to enable it to automaticallytake into a complementary draw-head, as will be presently described. Itwill also be seen that when the draw-head 13 is to be connected with anordinary draw-head through the medium of an open link the portion of thechain between the link D and arm inlay be shortened, so as to hold theouter end of said link in an elevated position and prevent it frominterfering with the operation of the ordinary open link in thehorizontal recess of the draw-head.

\Vhen it is desired to couple the car carrying the draw-head B with thecar equipped with the complementary draw-head B, it is simply necessaryto bring the cars together, when the outer end of the link D, carried bydraw-head B, will ride up the bottom wall b of the mouth (till drawhcadl3 and drop into the pocket (Z thereof.

Vhen it is desired to uncouple the cars, it is simply necessary for atrainman on top of the car to draw upon the chain F or one standing atthe side of the car to rock the shaft E in the direction indicated byarrow, so as to raise the end of the link from the pocket (I of thedraw-head B. This may be easily done when the cars are in motion and thelink D is subjected to draft, which is an important advantage.

It will be noticed from the foregoing that in the event of thedraw-heads B B resting in different horizontal planes the inclinedbottom wall I) of the mouth a in. the draw-head 13' will guide the onter end or head of the link to its seat in the pocket (10f saiddraw-head 13.

Having thus described my invention, what I claim is- In a ear-coupler,the combination of a carbody, a draw-head formed in one piece and havingthe recess 0 in its upper side comprising the mouth a corresponding inwidth and height to the draw-head at the outer end thereof and havingthe inclined bottom wall of concave form in cross-section and alsohaving the flaring side walls 0, the pocket (Z, and the longitudinalcentral groove f connecting the mouth and the pocket; said draw-headalso having the horizontal recess, at an intermediate point of itsheight, communicating at its outer end with the mouth a, and thevertically-disposed aperture intersecting said horizontal recess, thelink having heads at its opposite ends; one of said heads being designedto rest in the pocket d of the drawhead, a elevis disposedlongitudinally of the link, a bolt extending longitudinally through theouter head of the link and pivotally connecting the elevis thereto so asto enable the same to rock laterally on the link, the rockshaftjournaled in hearings on the end wall on the ear-body and having theforwardlyextending arm iand also having the upper and lower stop-arms t"1' adapted to engage the end wall of the ear-body, a chain eonneeted atone end to the elevis on the outer head of the link and at its oppositeend to the ear-body, and a bolt detaehably connecting the chain and thearm dot the rock-shaft, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
